Abstract

1366132 Thread tapping apparatus AVDEL Ltd 11 Jan 1972 [11 Jan 1971] 1238/71 Heading B3N A thread-tapping machine uses a bent tap 10 to roll threads in a succession of workpieces 54a, 54b, 54c. Workpieces are fed from a hopper 52 by gravity along the preferably translucent feed pipe 34 to a collet 32. The jaws of the collet are biased open and are closed by forward movement of a sleeve 40. Tap 10 is positioned in a holder 56 that can be reciprocated back and forth relative to the collet. A stop 42 prevents workpieces being ejected from the collet during reverse movement of the tap. The control arrangement for the various parts enables the movement of them to be halted whilst the collet continues to rotate.
